Latest Patents
Hofmann's latest patents focus on self-piercing rivets and the methods associated with their use. One of his key inventions is a self-piercing riveted joint that comprises an upper workpiece and a lower workpiece, along with a self-piercing rivet. In its undeformed state, the rivet features a head that defines a head diameter (DH), a shank that defines a shank diameter (DS), and a foot end opposite the head. The design includes a flat surface at the foot end, which faces away from the head, and an axial recess that is radially inward of the flat surface. This recess is partly defined in the foot end and is open axially away from the head, exhibiting a frustoconical shape in longitudinal cross-section. The axial recess has a defined depth (LB), and the ratio of the recess axial depth (LB) to the shank diameter (DS) is less than 0.3. In its deformed state, after the creation of the riveted joint, the rivet extends through the first workpiece and penetrates the second workpiece, with the head bearing against the upper surface.
